MPC's 140 Series Vertical End Turn Blockers
have been on the job for almost 40 years. Our experience and knowledge of
blocking applications from sub-fractional through integral horsepower stators
allows you to choose the exact blocker for your requirement from our wide
selection of field-proven models.

All MPC blockers are designed with cast platen and column construction
that provides maximum rigidity and assures accurate machine and tooling
alignment for years to come.

Our uniquely designed tooling, coupled with the sequential actuation
of tooling, massages the magnet wire into a homogenous shape by progressive
wire displacement, therefore avoiding damage to the wire and wire insulation.
For high-slot-fill stators with tight final forming dimensions, our models
with individual cuff support finger protection are available. The individual
cuff support finger maximizes the protection of the slot cell insulation
by maintaining clearance between the iron and the windings, which also assures
adequate clearance for the lacing needle.
